Pure silicon insulator

Pure silicon insulator is used increasingly in the power industry nowadays, it is very important to know the behavior under different environmental conditions of pure silicon insulator.

Pure silicon insulator

In the early age, most insulator are made of porcelain or ceramic material, but it is weak and bad performance in the pollution area, the porcelain insulator also to heavy and it is hard to installation, so pure silicon insulator are be used by the engineers, the chemical changes in the insulation, in the electric field is facilitated.

The surface contamination of pure silicon insulator is the biggest problems in outdoor applications, when contamination build-up is exposed to moisture, an excessive leakage current, dry band arcing and eventually to flashover, the pure silicon insulator can be more effective, offering much better long-term resistance, to contamination and moisture.

Pure silicon insulator designed with silicone rubber have been found to reduce the need for maintenance in area of moderate to high contamination, free fluid in silicone rubber is the key to another important surface characteristic of silicone rubber, the microscopic diffusion of fluid serves to encapsulate contaminant particles an prevent moisture absorption.

The Pure silicon insulator hydrophobic fluid migration helps maintain a high surface resistance an water-shedding ability.
